T all whom, it may concern.-

Beit known thatLRoBERTHERMAN J AHNs, of Miami, in the county of Roberts and State of Texas, have invented a new and useful Im. provement in a Combined Rake and Stacker, of which the following is a specification.

My invention is designed to provide a horserake for hay, &c., which shall be so constructed as to enable it to be used for loading the hay onto the wagon or piling it onto a stack; and it consists in the peculiar construction and arrangement of the various parts of the same, which I will now proceed to describe with reference to the drawings, in which- Figurelisaperspective View from the rear, showing in dotted lines the position of the rake when elevated and turned to one side for loading or stacking. Fig. 2 is a detail, partly in section, showing the rake and rakehead in its relation to the mast. Fig. 3 is an enlarged sectional view on the line 3 3 of Fig. l. Figs. 4 and 5 are respectively views of the clutch mechanism and main driving-wheel under Ythe mast. Fig. 6 is a cross-section on line' 6 of Fig. 5, and Fig. 7 is a detail in perspective of the rake-head and tripping mechanism. y

In the drawings, Fig. l, A A represent two parallel bars arranged in the line of draft and bolted or otherwise connected in the rear to two bars A A2 at right angles, which bars A A2 at their outer ends are connected by a' cr0ss-bar A3, the whole forming the'main frame of the device. This main frame is supported by three Wheels, which run upon the ground. One of these, B, is under the outer end of the bar A. The other one, B', is under the rear ends of the bars A A, and the other one, B2, is journaled on anarm projecting from the forward end of the bars A A on the opposite side from the rake. Between the front ends of the parallel bars A A is jointed the tongue C, to which is connected, in the usual way, the draft attachment for the e team.

ciently close to the ground to gather'up the Vsprocket-wheel d4.

l hay o'r grain as the machine is dragged forward by the team across the field. When a sufficient quantity of hay or othermaterial is gathered, the rake is to be raised upon the mast M, the mastk rotated about its vertical axis till the rake occupies the position shown in dotted lines, and the rake is then dumped either uponthe wagon or stack.

I will first describe the means for raising and turning the rake.

The rake (see Figs. 2 and 7) has a head formed of two horizontal hollow metal rods R' R', having Vertical transverse pieces R2, to which head is firmly fastened in the middle thel metal framework D. This framework has firmly attached to its upper end a strong Sleeve D', which slides vertically on the mast M and has a groove g, Fig. 7, that lits a longitudinal feather or spline d, extending the full length of the mast. This rake and its frame D are suspended and raised and lowered by a yoke e and a rope F.. This rope is attached to the yoke and extends over a pulley E at the top of the mast (see Fig. l) and thence descends to and is wound upon a windlass W. This windlass is connected by suitable gears to the driving mechanism, and when it is turned it winds up the rope E and raises the rake along the mast. To hold the rake in its elevated position, a pawl w is made to engage the ratchet-wheel w on the end of the windlass, and when the rake is to be lowered4 the pawl is withdrawn from the ratchet by a ropev 102 and a pull-rod w3, extending to a lever -w4 near the drivers seat. The windlass is rotated (see Figs. l and 3) by a gear-wheel a on its endl meshing with a pinion a/on the same shaft with a sprocket-wheel 01.2, which derives motion through a chain belt a3 from a The sprocket wheel a4 (see Figs. 4 and 5) is formed on or rigidly attaehed to a sleeve S, sliding on a shaft F, j ournaled in hangers under the frame-bar A. To this shaft is rigidly attached the main running and driving-wheel'B. This wheel is located nearly under the mast M, so that the weight of the load on the rake will come directly over the wheel B and hold it to the ground iirmly enough to insure its positiveV rotation, so as to drive the windlass-gears IOO with power. Beside the driving-wheel B there is formed a clutch-section y, and on the end of the sleeve S is formed another clutch-section which may be thrown into or out of engagement with the clutch-section y. When these clutch-sections are engaged, the rotation of wheel B turns the sleeve S and the sprocket wheel a4 and through the chain belt the windlass-gears. To hold the clutchsections engaged, a helical spring H is arranged on shaft F to force the sleeve S and its clutch-section a: toward the other clutchsection y. When the rake has been raised and its load dumped, the rake is to be lowered. To do this, the pawl is first removed from the ratchet of the windlass, the clutches separated, and the windlass allowed to run backward, as the rake descends of its own weight. To separate the clutches, a swiveling collar or fork c embraces the sleeve behind its flange s, and the sleeve is pulled back against the spring H by means of a pullrod c', connected (see Fig. l) to a lever c2 near the drivers seat. To regulate the descent of the rake, a friction-brake strap G, Figs. 4 and 5, embraces the sleeve S and is tightened thereabout (see Figs. l and 5) bya rope Z), pullrod b', and treadle b2 near the drivers seat.

I will now describe the means for rotating the rake about a vertical axis, so as to dump it to one side after having been raised. For this purpose the vertical mast is stepped in a bearing o on the frame-bar A (see Fig. 3) and has rigidly attached to its lower end a sprocket-wheel m, around which passes a chain m', Fig. 5, whose two ends are attached to two parallel rods m2 m2, Fig. l, running to two levers m3 m3 near the drivers seat. By pulling on one of these levers and pushing the other the mast is rotated in the step and may be turned first in one direction and then in the other, and being connected to the sleeve of the rake-head by the feather the rake swings with the mast. The upper end of the mast swivels inside of a collar Z, which is held and stayed to the framework by guyrods Z Z Z.

After the rake has been raised and turned around to the dotted position in Fig. l it is dumped as follows, reference being had especially to Figs. 2 and 7. A spring-bolt n, with a beveled face, slides vertically in the frame D. The bolt is heid up by the spring n and is drawn down by the level` n2, pivoted on one side of its fulcrnm to the lower end of the bolt and on the other side attached to the rope n3, which passes around the pulley n4, and thence (see Fig. l) passes to a standard n.5 and through an eye in its top goes to a pulley ns near the tongue and then extends back to and is secured to any portion of the framework. Referring again to Fig. 2, the upper member R of the rake-head is locked behind the bolt n, as shown in dotted lines, while the rake is rising with its load. When the load is to be dumped, a pull on the rope n3 draws down the bolt n, and the weight of the hay on the rake causes it to drop to the position shown in full lines in Fig. 2, which allows the hay to slide olf. When relieved of the weight of the hay, the rake rises to the dotted position again, and the upper member R of its head passes over the inclined face ot' bolt n and is locked behind it. The power to do this is furnished by two springs V V, Figs. l and 7, connecting the upper member R 'of the rake-head to braces D2D2 from the frame D. By extending the trip-rope n3 to various parts of the framework it may be seized to dump the load from various points where the operator happens to bc.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-
